Note.

The Analog I/P tab is displayed only if Source ID for the Recording Channel is set to an analog
signal source – see Section 7.9.1, page 86.

If an analog input is assigned to more than one recording channel, changes to any of its
parameters and tags are applied to each channel the input is assigned to.

If an analog input is already assigned to another channel, the edit keys (

Select the electrical characteristics of the input.
Select the input type required.
Note.

Simulated input types are available for evaluating recorder features
without the need for process connections.

If Volt-free Digital Input or 24V Digital Input is selected, the input
channel becomes a digital input channel – see Section 7.9.3,
page 94.

Select Off to disable an analog input.
Warning. Ensure that the appropriate electrical connections have been
made – see Section 3.3, page 14.
Select the linearizer type used to condition the input signal before it is
sampled.
Note. For thermocouple applications using an external fixed cold
junction, set to millivolts and select the appropriate linearizer type.
